Abstract

Dans certains modes de réalisation, un système chirurgical ophtalmique de visualisation d'un ?il comprend un microscope ophtalmique et un dispositif laser. Le microscope ophtalmique reçoit la lumière réfléchie ou diffusée vers l'arrière depuis l'intérieur de l'humeur vitrée de l'?il afin de fournir une image d'un objet à l'intérieur de l'humeur vitrée. Le microscope ophtalmique comprend une source d'éclairage en fente (qui comprend une source de lumière et un élément optique), un filtre spectral et des oculaires. La source d'éclairage à fente éclaire l'?il avec de la lumière, la source de lumière fournissant la lumière, et l'élément optique dirigeant la lumière dans l'?il. Le filtre spectral filtre les composantes spectrales rouges de la lumière. Les oculaires reçoivent la lumière provenant de l'?il afin de fournir l'image de l'objet. Le dispositif laser génère un faisceau laser à diriger vers l'objet à l'intérieur de l'?il.
